To all whom it may concern:

Beit known that I, MAX DOERFEL, residing at Klingenthal, in the Empireof Germany, have invented a new and Improved Harmoni- 5 ca, of which thefollowing specification is a full, clear, and exact description.

Fig. 4 is a longitudinalsection of a modification; Fig. 5, a section on line y y, Fig. 4, andFig. 6 a section on line x x', Fig. 4.

The lettera represents the upper plate, and b the lower plate, of aharmonica. c is the reed-plate interposed between them. Each of theplates a b is provided with a dovetailed mortise at its right and leftedge, and when the two plates are placed upon each other their mortisescommunicate, as seen in Fig. 2.

d d are a pair of plugs, having Shanks of' double-dovetail form to twithin the mortises between plates a b. The plate c is notched oppositethese plugs, and the plugs are of such a length as to enter the notches.

In use the parts a b c are placed in proper position, and then the plugsd are inserted to bind them all together.

In Figs. 4, 5, and 6 I have shown Ushaped clasps e, which embrace theedges of the plates a b.
